The posttranslational alterations of proteins may include the addition of polysaccharides to proteins (Option 4).

<h3>What are posttranslational alterations of proteins?</h3>

The posttranslational alterations of proteins are different modifications in the protein sequences in order to activate their functions and or suppress them.

One of the most common posttranslational alterations of proteins is phosphorylation, which occurs at specific amino acid residues and it is able to activate or deactivate proteins in order to change the signaling pathway associated with their functions. Polysaccharides can also be added to proteins in order to change their functional states.

Therefore, with this data, we can see that the posttranslational alterations of proteins are able to modify the functional properties of a protein and polysaccharide addition in one of these types of modifications that both structural proteins and enzymes suffer to activate an or deactivate them.

nika2105 [10]

It is because little kids and toddlers copy everything that they see other people do.  If they see you doing something, then they think they are supposed to do it too, and they copy you. Also they are “like sponges”(that’s what my mom says) and “soak up(/remember) everything”.
